drm: Add an hx8367d tinydrm driver.

2018-10-30T23:23:38+00:00

I want to sort out support for tinydrm in vc4, so I needed to get a tinydrm-appropriate panel working and this is what I had on hand. This is derived from a combination of ili9341.c from tinydrm and fb_hx8357d.c from staging's fbtft. v2: Write my own register defs from the spec to not need the header from fbtft. Fix spi device string to enable module autoloading.

drm/tinydrm: add backlight dependency for ili9341

This tinydrm driver fails to link without the backlight support: drivers/gpu/drm/tinydrm/ili9341.o: In function `ili9341_probe': ili9341.c:(.text+0x578): undefined reference to `devm_of_find_backlight' Fixes: 3fa0e8f6f960 ("drm/tinydrm: new driver for ILI9341 display panels") Signed-off-by: Arnd Bergmann Acked-by: Noralf Trønnes Signed-off-by: David Lechner Link: https://patchwork.freedesktop.org/patch/msgid/20180709152106.990066-1-arnd@arndb.de

drm/tinydrm: new driver for ILI9341 display panels

2018-06-27T18:03:45+00:00

This adds a new driver for display panels that use the Ilitek ILI9341 controller. It currently supports a single display panel, namely the YX240QV29-T (e.g. Adafruit 2.4" TFT). The init sequence is from the Adafruit Python library for the ILI9341 controller. https://github.com/adafruit/Adafruit_Python_ILI9341 Signed-off-by: David Lechner Reviewed-by: Andy Shevchenko Reviewed-by: Noralf Trønnes Link: https://patchwork.freedesktop.org/patch/msgid/20180525193623.15533-5-david@lechnology.com

tinydrm: add backlight dependency

2018-02-28T20:08:56+00:00

Calling devm_of_find_backlight directly means we get a link failure without CONFIG_BACKLIGHT_CLASS_DEVICE: drivers/gpu/drm/tinydrm/mi0283qt.o: In function `mi0283qt_probe': mi0283qt.c:(.text+0x684): undefined reference to `devm_of_find_backlight' This adds an explicit Kconfig dependency for it. While I did not observe that failure for st7735r, I assume the same change is needed there for the same reason.

drm/tinydrm: Replace tinydrm_of_find_backlight with of_find_backlight

2018-02-20T16:07:22+00:00

Remove tinydrm_of_find_backlight from tinydrm-helpers.c. We now have a generic of_find_backlight defined in backlight.c. Let the callers of tinydrm_of_find_backlight call of_find_backlight. Also, remove select BACKLIGHT_LCD_SUPPORT and select BACKLIGHT_CLASS_DEVICE from tinydrm/Kconfig as it is a hack that is no longer needed.
